The structure and mathematical model of VSC converter are discussed. When performing DC power flow calculation, the converter station is equivalent to P node/Slack node/D node according to different control modes of the converter station. And the non-linear DC network equations is solved with the Newton-Raphson (NR) method.

HVDC Control System - Overview

Principles of HVDC Controls Control of DC Voltage • DC voltage is varied by means of a converter bridge • In rectifier operation the power flow is from the AC system to the DC system • The power flow is changed from the DC system to the AC system by reversing the DC voltage. • The DC current does not change it’s direction. • The operating range of the ideal converter -theory from 0

HVDC converter station - Wikipedia

An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains: . three-phase alternating current switch gear

Boone County Watchdog: 01/25/16

At the heart of an HVDC converter station, the equipment which performs the conversion between AC and DC is referred to as the converter. Almost all HVDC converters are inherently capable of converting from AC to DC (rectifiion) and from DC to AC , although in many HVDC systems, the system as a whole is optimised for power flow in only one
